The development of the horticultural industry is largely limited by disease and excessive pesticide application. MicroRNAs constitute a major portion of the transcriptomes of eukaryotes. Various microRNAs have been recognized as important regulators of the expression of genes involved in essential biological processes throughout the whole life cycle of plants. Recently, small RNA sequencing has been applied to study gene regulation in horticultural plants. In this review, we summarize the current understanding of the biogenesis and contributions of microRNAs in horticultural plant disease resistance. These microRNAs may potentially be used as genetic resources for improving disease resistance and for molecular breeding. The challenges in understanding horticultural plant microRNA biology and the possibilities to make better use of these horticultural plant gene resources in the future are discussed in this review.
园艺产业的发展在很大程度上受到病害和过度施用农药的限制。微小RNA构成了真核生物转录组的主要部分。各种微小RNA已被公认为是植物整个生命周期中参与基本生物学过程的基因表达的重要调节因子。最近，小RNA测序已被应用于研究园艺植物中的基因调控。在本综述中，我们总结了目前对微小RNA在园艺植物抗病性中的生物合成及其作用的理解。这些微小RNA有可能用作提高抗病性和分子育种的遗传资源。本综述讨论了理解园艺植物微小RNA生物学所面临的挑战以及未来更好地利用这些园艺植物基因资源的可能性。
